Cautions:
– When reverse or quick restore resync operation ends abnormally, or,
Suspend pair is requested during reverse copy or quick restore, the pair
status changes to suspended. The S-VOL of the suspended pair is
read/write-enabled for all hosts; however, the data on the S-VOL is not
guaranteed. The T-VOL of the suspended pair remains read/write-
disabled.
– Even when reverse or quick restore resync operation ends abnormally,
or, Suspend pair is requested during reverse copy or quick restore, the
status of other SIz pairs which share the same S-VOL does not change.
– After an SIz reverse copy or quick restore operation is performed, make
sure that the pair status changes to duplex before performing a TCz
resume pair operation. If you perform the TCz resume pair operation
before the pair status changes to duplex, the command (resume pair
operation) will be rejected.
